Khoa Sagor Dighi (Khoa Sagor Dighi) is located on the east side of Lakshmipur Raipur road in Dalal Bazar area of Laxmipur Sadar Upazila. Spread over an area of about 25 acres, the lake appears shrouded in mist from one end to the other. For this reason, the Dighi is called Khoya or Misty Dighi in the local language of Lakshmipur. According to the locals, around 200 years ago, Brajavallav Roy, the landlord of Dalal Bazar, dug this lake around 1755. Later, zamindar Raja Gaur Kishore Roy renovated the pond.
There are many legends associated with this ancient lake. It is said that a bridegroom was crossing Dighi with his bride. At that time, when the bridegrooms got thirsty, they went down to drink water by the lake. But when the bride goes down to the bank of the lake to drink water, something strange under the lake grabs the bride's feet and drags her into the deep water. Locals believe that after this incident, the pond has become such a deep hole that even in severe drought the hole does not dry up. Next to Khowasagar Dighi there is another Dighi called Kodal Dha Dighi and Dalal Bazar Mutt.
The traditional Khowsagar Dighi has become popular as a tourist attraction in Lakshmipur. Numerous trees have been planted on the bank of the lake for beautification. In the evening, when the west and east sides of the lake are lit up, the scene is even more beautiful. Due to the clear water and pleasant environment of the lake, many entertainment lovers come to visit the banks of this beautiful lake every day.
